2. Circuit Description 2-1. SGH-E350E RF Circuit Description 2-1-1. RX PART - FRONT END MODULE(ANTENNA SWITCH MODULE + RX SAW FILTER) (U101) → Switching Tx, Rx path for GSM900, DCS1800 and PCS1900 by logic controlling.
Circuit Description 2-2. Baseband Circuit description of SGH-E350E 2-2-1. PCF50603 (U400) - Power Management Eight low-dropout regulators designed specifically for GSM applications power the terminal and help ensure optimal system performance and long battery life. A programmable boost converter provides support for 1.8V, 3.0V SIMs, while a self-resetting, electronically fused switch supplies power to external accessories.
Circuit Description 2-2-3. Key This is consisted of key interface pins KEY_ROW(0:4) and KEY_COL(0:4) in PCF5213EL1. These signals compose the matrix. Result of matrix informs the key status to key interface in the PCF5213EL1. Power on/off key is seperated from the matrix. So power on/off signal is connected with PCF50603 to enable PCF50603. Key LED is consisted of sixteen blue LEDs. key LED use the 3.3V LDO(U606) for a supply voltage. KEY_LED_ON signal enables eight white LED.
Circuit Description 2-2-9. PCF5213EL1(U200) The PCF5213EL1 is mainly composed of embeded DSP and ARM core. The DSP subsystem includes the Saturn DSP core with embedded RAM and ROM, and a set of peripherals. It has 24kx16 bits PRAM, 104k*16 bits, 32k*16 XYRAM and 63k*16 XYROM in the DSP.
